Why is Camilla being crowned alongside King Charles and what to expect from the ceremony

sovereigns have been crowned for 1,000 years — eight months after the monarch’s accession and the death of the Queen.No reason has been given for why the date has been chosen, just that it was decided upon in agreement with the royal family, the UK government and the Church of England.May 6 is also the birthday of the Duke and Duchess of Sussex’s son Archie – King Charles III’ grandson – who will be turning four on the day.The date was the wedding anniversary of the late Queen’s sister Princess Margaret, while the King’s grandfather George VI held his coronation in the month of May.As is traditional, Archbishop of Canterbury, Justin Welby, will preside over the deeply religious affair.Only eight months ago, the plan was not for Camilla to be crowned Queen Consort at Charles' coronation.But the Queen changing her mind about her daughter-in-law's future status changed all that.Upon the 70th anniversary of her own coronation in February, the late monarch released a statement saying: "When, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support you have given me."And it is my sincere wish that, when the time comes, Camilla will be known as Queen Consort as she continues her own loyal service."The announcement shocked royal watchers, who expected Camilla to have a much more low-key title.

It marked a change of course in the thinking of the Queen, who is devoutly religious and head of the Church of England.The Queen was said to be deeply uneasy about Camilla, who was Charles’ former mistress, becoming his spouse following his messy divorce from Diana.But after seeing Camilla's dedication up close since their marriage in 2005, the Queen's positioned softened in her.
